APPARATUS FOR THE MANUFACTURE OF CARBON-BLACK.

SPECIFICATION forming part of Letters Patent No. 726,341, dated April 28, 19031. Application filed December 22,1902. Serial No. 136,283. (No model-ll which will enable others skilled in the art to.

which it appertains to make and use the same.

This invention has general reference to improvements in machinery in the manufacture of carbon-black or lampblack, as it is generally known; and it consists in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate my improved apparatus more fully, Figure 1 is an elevation of so much of an apparatus as will illustrate my invention, a portion of which is shown in vertical section. Fig. 2 is a plan view showing depositing-plates employed by me. Fig. 3 is a cross-section on the line X X of Fig. 1.

Like numerals of reference indicate corre sponding parts throughout the figures.

The object of my invention is the production of a suitable mechanism for the economical manufacture of carbon from,preferably, natural gas. To attain thisresult, the devices which I employ are constructed within a suitable building, and the particular apparatus by means of which the carbon-black is produced comprises a series of depositingplates 1, which preferably are annular rings 2 and 3. The rings 2 are formed integral by spokes or radial arms with a hub 4,- revolubly mounted on a stationary support or shaft 5, and the rings 3 lie outside of rings 2 and are made a part of such rings through the web 6 and in such a manner as to provide an annular opening 7 of great width between the inner and outer edges of the plates 3 and 2, respectively. The rings 2 and 3, which form the plate 1, are so disposed with reference to each other that while the ring 3 lies beyond the outer circle described by the ring 2 itis elevated to some extent above the same, and the lower faces of each of the rings are beveled, as shown at 8. The shafts or supports dare suitably supported at their lower ends and at their upper ends have bearing on the frame-support 9 and in jonrnaled boxes 10, which said boxes are held under yielding pressure by means of springs 11, hearing between a plate of the boxes and a support 12, for the purposes which will now be described. It is designed to rotate the plates 1 by means of a friction-drive, comprising a friction-pinion 13, supported on a suitable drive-shaft 14, which said shaft may receive its power in any suitable manner; but for convenienceI have provided the wormwheel 15 and the worm 16, the latter designed to impart movement to the worm-wheel15 from a suitable source of power. This shaft may have a bearing for its lowerend, as shown at 17, and an additional hearing at 18 upon the frame 9. The peripheral edges of the rings 3 are designed as frictional bearingsurfaces, which frictionally engage the pinion 13 and are driven thereby. This is one means of imparting power to the depositingplates; but other desirable and convenient means may be employed; but when employing a friction-drive it is preferable to use a yielding pressure device for the shaft 5 or' otherwise employ it for holding the .plates 1 in frictional contact with their drive-pinion.

Suitably supported beneath the plates and lying a suitable distance beneath the rings forming such plates and approximately beneath the center of such rings are annular burners 19 and 20, and 21 and 22 are feedpipes suitably connected with the burners aforementioned, that are fed from a source of supply, (indicated as 23.) The jets of such burners when the burners are disposed as has been described will direct the flame and cause it to spread over thesurface formed by the rings 2 and 3, and the spread of flame will be such that the smoke therefrom passes up around the opposite edges of the rings and is directed through the annular opening 7, formed by the outer and inner edges of the rings 2 and3. Attention is now directed to the purpose of the lower beveled faces 8 of the rings, which is such that the escape of IOC the surplus carbon from the flame will be directed toward the inner edges of the rings 2 and 3 and the carbon liberated by the burners 19 will pass up through the annular space 7 and that produced by the burners 20 will pass up between the spokes or radial arms which support the rings 2. I have provided for removing the carbon from the lower faces of the rings 2 and 3, which is scraped therefrom by scrapers 24 and caught by a hopper 25 and carried to asuitable receiving-receptacle (not shown) by means of a suitable conveyer 26. The hopper is supported by the frame 9, which passes through the same, and the frame 9 is supported upon the uprights 27. I have provided a series of conical depositing-fines, (indicated as 28,) having their upper and lower ends open. These flues are supported for rotation on a support 29, having its lower end fixedly secured in the upper extreme ends of the shafts 5, and the outer ends of the supports 29 have a bearing at 30 in a suitable frame-support 31. 32 and indicate spiders carried by supports 29 and engaged in a suitable manner by the walls of the conical fines 28, by means of which the said fines are rotatably mounted on supports 29. The upper spiders 33 may be arranged with contracted or enlarged openings-whereby the draft through the fines may be regulated. The disposition of the conical fines 28 is at an angle bearing obliquely to the central vertical line or axis of the shafts- 5 ,which cause the lower edges of the fines 28 to bear obliquely or diagonally from the upper surfaces of the rings 3. The lower edges ofthe fines 28 have the outwardly-presented rolled portions 34, substantially as shown in the figures, and the tilt of the flues is such as to cause a portion of the lower rolled faces 34 at all times to frictionally engage the upper surface of the rings 3, by means of which through the rotation of the plates 1 the flues '28 are slowly revolved. The upper faces of the rings 2 and 3 are arranged parallel with their lower faces, as shown in the drawings; but they may, if desired, instead of presenting an upperbevel face lie horizontally, and in this I do not wish to confine myself. It will be observed that in providing a collectingflue of cone shape bearing obliquely to the axis of its main support 5 all carbon escaping and allowed to pass from beneath the lower faces of the rings will pass up into the tines and will be deposited on the surface of the fines against which the carbon is directed.

To insure that the carbon escaping from the rings shall be directed to the fines, I have provided 'a stationary shield 35, overhanging the rings forming the plate, which will receive and direct the carbon from the plates to the fines somewhat in the manner shown in the sectional portion of Fig. 1. This shield is supported in a suitable manner from the support or shaft 5 by means of the radial arms For depositing the carbon in the manner described on the inner surface or wall of the fines 28 I also provide for scraping the same therefrom and collecting it at a suitable point on the upper surface of the rings 3. The scraper by means of which this is accomplished is indicated as 37, supported in a stationary manner from the support 29 by means of the braces 36, as shown, and upon the scraper 37 I have provided a series of cleats 38, disposed at suitable points thereon, which form sloping pockets toward the wall of the fines 28, which receives to some extent the'bulk of the carbon scraped from the wall of the flnes and retards the downward movement thereof and permits the carbon .to be gradually deposited onto the upper surface of the plate 3, which will also prevent the carbon from being blown and deposited at every other place besides the point where it is intended to be received on the plate 3. By employing the upper surfaces of the plates or that portion thereof indicated by the rings 3 it is necessary to also provide for the removal of the carbon therefrom and deposit the same in the hoppers 25. For this purpose I have provided suitable scraping means 40, which overhang the upper surface of such plates and are disposed in such a manner that as the plates rotate the carbon deposited thereon from the fines will be brushed off andpermitted to fall into the hoppers 25, and to insure the carbon brushed off ofthe upper surface of the plates being deposited in the hoppers 25 I have provided the lateral extensions 41 therefor.

In the apparatus which I describe and show herein I have providedfor collecting the finest particles of the carbon, which it has not heretofore been able to attain. By constructing the plates so that they have an upwardlyplaced cone or beveled surface theocarbon which is not deposited on the surface of such plates will be directed to the interior of the fines 28 and deposited thereon. I am aware of various forms of plates and collecting-s11 rfaces which have been provided; but I am not aware of any plates of the formation which I show nor the provision of a rotating depositing-fine for collecting theescaped carbon for which I provide and a scraping means within such flue for freeing the carbon therefrom and depositing it onto the upper surfaces of the plates and in scraping it therefrom, and I do not wish to be confined to the details of construction and arrangementherein, as various changes may be made without IOU 2.
